SNOW-PLOW.

SPECIFICATION forming part of Letters Patent No. 300,016, dated Junelo,1884.

' Application nica Maren 21, iss-i. (No moda.)

To a/ZZ whom t may concern:

Beit known that I, J AMES HENRY RUssELL, of St. John, in the county ofSt. John, and Province of New Brunswick, Dominion of Canada, haveinvented 'new and useful Improvements in Snow-Blows; and I do herebydeclare that the following is afull and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

The objects of this invention are to do away with the resistance to themotion of the plow I accruing from pressure and friction of the snowagainst its sides; economy of power for driving the same; a higher rateof speed, and more thorough execution than `is attainable by thesnow-plows of different construction in general use. These results areachieved by the mechanism illustrated in the drawings, herewith filed aspart hereof, in which the same letters of reference denote the sameparts in all the views.

Figure l is a top View. Fig. 2 is a side elevation, partly in section.Fig. 3 represents sectional views of parts detachedV for illustratingfeatures of construction not fully shown in the other figures.

A A is a chisel-shaped point, made of steel and boiler-iron, extendingentirely across the front of the plow, and secured to the frametimbersby bolts or screws a, the object thereof being to lift the snow in astraight line from one side ofthe track to the other. The plowpointmaybe made with a convexed curve 5 or it may have an angled or a doubleangled point.

B represents a heavy sponsing at each side of the plow, constructed ofpitch-pine, about ten inches thick and twelve inches wide, and bolted toand on the outside of the grade-timbers. Beginning atthechisel-point,the plow is graded at an angle of about thirty degrees, or about onefoot in two, to a distance of eight feet, more orless,) and there curvedand forming arcs for the remaining distance, the chord of which is abouttwelve feet and the rise six inches, so that the upper end of thesponsings hanging guards or frame-work at the bottom of the plow.

Dis a centrally-located iron cutter of triangular form, with curved baseand head. It is constructed of boiler-iron of suitable thickness, andbegins about three feet from the chisel-point. It extendsup the center,where it is bolted to the frame timbers through the sheathing of theplow. The object of this feature of construction is to cut and dividethe snow after the chisel-point has entered and raised it from thetrack, and throw it to each side and clear of the same.

C C are heavy iron plates suitably secured by bolts or screws to eachside of the plow, and having upright flanges G C extending about eightfeet along the upper sponsings, for the purpose of holding the snow onthe plow and carrying it from five to seven feet above the road-bedbefore it is discharged. From thence the plates C C conform to the bodyof the plow, and extend to the top of the upper deck,I, where their endsare suitably secure'd. The plates C C are made of boiler-plate irontwelve inches wide, and screwed or bolted to thegrade-timbers. The angedparts C C are to be of steel, welded thereto, and should be at leastthree incheshigh and one-fourth of an inch thick. p V

E E are wings, to be made of iron onefourth of an inch thick,substantially in the form shown, and suitably secured in the positionshown. The object of this feature of c011- struction is to throw thesnow a long distance from the track and to prevent the locomotive frombeing showered with snow, and also to protect the man onthe upper deckin charge of the plow.

E is a coupling-bar of suitable length, having a metal finish, G, at itsinner end, which fits within a corresponding piece, G', on theprojecting frame-timber F', ending midway between the axles of theforward truck. The parts are perforated for the reception of the king-bolt H, thus forming a semicircular socket-j oint for applying thepropelling-power to the forward part of the plow, andV allowing it toturn curves easily and avoid being thrown from the track. Thesemicircular socket-joint connection may be made independent of theking-bolt of the truck. The coupling-bar F roo is to be made ofpitch-pine twelve inches wide and ten inches thick, and should be abouttwenty feet long. The rear of the plow-frame is provided with a slot ofsufficientA length to allow unobstructed oscillation of the couplingbarwhen the plow is turning curves. The outer end of the bar E should beprovided with suitable meansY of connection with the locomotive. 4

By reason of the sponsings B B projecting from the sides of theplow-frame, and the chiselpoint extending across the same, the cut ofthe plow will be so wide that the sides thereof will be relieved of thepressure and friction of thesnow, and the plow can be driven with lesspower and at a higher rate of speed.

Having explained the construction and operation of my improvement, whatIclaim as new, and desire to secure by Letters Patent, is

1. The combination, with the sides of the plow, of the curved sponsingsB, applied thereon, and the sheathing C, Ysupported thereby at itsmargin, to cut wider than the plow itself, substantially as described.

2. In a snow-plow, the long coupling-barF, projected far forward andconnected to the frame-timber E at a point forward ofthe center of theplow, substantially as described.

3. rlhe combination ofthe coupling-bar E and the frame-timber E', unitedby the semicircular socket-joint connection Gr G, substantially asspecied, for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES HENRY RUSSELL.
